The 5501-467 is a high-capacity power supply module developed by Woodward, Inc. for MicroNet Plus and MicroNet Simplex control platforms. It converts high-voltage industrial AC/DC power into regulated low-voltage 5 VDC logic power for control processors and I/O modules.
This module is optimized for Simplex system architectures, providing stable power delivery for turbine control, engine control, and large mechanical drive systems. It features intelligent thermal management with automatic current derating and front-panel LED diagnostics for quick maintenance assessment.
The module is designed for harsh industrial environments and supports high-altitude operation up to 4,000 meters, making it suitable for remote power generation sites.

Utility-scale power generation control systems
Gas and steam turbine control skids
Large mechanical drive automation systems
Remote or high-altitude power sites
Can this be used in redundant power configurations?
No. This module is designed strictly for Simplex operation. Redundant systems require a dual-supply power architecture.
Why does output current decrease at higher temperatures?
Thermal derating protects internal components from overheating and extends module service life.
Does it support 110V AC input?
No. The module requires 180–264 VAC high-voltage input.
